Exact excerpt

Here, we show that the Margin unit explored at high elevations (>−2350 m) has a texture and chemistry indicative of a slow-cooled, crystalline, olivine-rich rock without significant water exposure. In contrast, exposures situated below the hypothesized Jezero paleolake’s second terrace level reveal a complex history of water-rock interaction.
